We will hold competitions between the public at large to decorate metros and buses. After a vote on the proposals by the public, the artist will be commissioned to create the art piece. Starting with one train car per line, the innovation will be expanded, if successful/popular/incentivising people to use public transport.
As the innovation is an opportunity for emerging artists to promote and express themselves, the artist will not get paid. Therefore, costs are kept low, comparable to maintaining the metro car. Potential collaboration with art schools advocated.
